1 Claim. (Cl. 160-92) This invention relates to closure devices and has particular reference to a closure device in the form of an exterior door and with the door being provided with a pair of separately shiftable panels.

The invention contemplates a door construction wherein the frame of the door is provided with a pair of stepped openings and whereby to support in flush relation to the outside, a solid panel and to support in flush relation with the inner side an insect screen frame and with each of the panels being hinged in a novel manner whereby the screen frame may be swung inwardly to permit the solid panel to be swung inwardly also and disposed out of the path of the swinging movement of the screen panel so that the screen panel can be subsequently moved into its particular opening.

The invention provides a very novel form of door construction having the separately swingable panels, with one panel being of solid construction to be exposed in closure relation to its respective opening to constitute a finished panel door for ornamental purposes and to prevent the entry of the elements and with the solid panel being movable in hinged relation to the door frame so that the screen frame can be shifted and latched in position to constitute a screened door, the solid panel being at all times hingedly connected to the door frame and movable with the door frame during the normal operation of the door.

The invention also contemplates a novel stepped hinge connection for the solid panel that will be disposed in recessed relation when the solid panel is closed to be substantially flush with the opening for the screen panel.

Numerous attempts have been made to provide combined screen doors and solid panel doors and whereby to function as a screen door and also as an ornamental closure door having all of the characteristics of a solid closure device from the outside.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

Figure 1 is an inner side elevation of a door constructed in accordance with the invention, parts being broken away for purpose of illustration,

Figure 2 is an outer side elevation of the device,

Figure 3 is a view similar to Figure 1 but with a solid closure panel being disposed in open position,

Figure 4 is a transverse section taken on line 44 of Figure 1,

Figure 5 is a transversesection taken on line 55 of Figure 3 and,

Figure 6 is a fragmentary perspective view of one corner of the door and a solid closure panel shifted to open position and illustrating a novel form of stepped hinge device.

2,975,838 Patented Mar. 21, 1961 Referring specifically to the drawings, the numeral 5 designates parallel stiles, 6 a header and 7 a sill, all connected together in any desirable manner to form an open frame. The stiles, the header and sill are cut away to form stepped openings 8 and 9. The opening 8 is adapted to be covered and uncovered by a relatively solid panel 10, being proportioned to be shiftably engaged into the opening 8, in a manner to be presently described. The outer side of the door is provided with suitable stop strips 10 around the periphery of the opening 8 and that partially overlies the opening to form astop for the panel'10. The panel has been here illustrated as being a solid wood panel although, it will be apparent that this panel may constitute a separate frame for any desirable translucent or transparent panel such as glass. The panel 10 is hingedly connected to one stile 5 by a novel form of stepped hinge device, illustrated as a whole by the numeral .11. The hinge 11 embodies stepped leaf sections 12 and 13, pivotally connected together by a pintle 14. The stepped leaf 13 is connected to one edge 10b of the panel 10, by screws or like fastening devices. The leaf 12 is recessed into the stile 5, shown more clearly in Figure 6. The recessing of the leaf 12 permits the leaf 13 to be swung downwardly in overlying relation thereto so that the leaf 13 will lie substantially flush with the openings 8 and 9. The leaf 12 is fixedly connected within the recess by screws or likefastening' devices, as is well known. Any suitable flush latch device 15 is connected to the opposite side of the panel 10, to engage a keeper 16 that is disposed in the opposites'ide of the opening '8 and, with the novel form of hinge 11 and the flush latchi15, the panel 10 may be shifted into closure position, ,as illustrated in Figure 4 so that its inner side will ,lie substantially flush with the stepped opening 9. j;

Hingedly connected at 17 upon the opposite stile 5 and movable into and out of the opening 9, is a frame 18,

preferably carrying an insect screen panel 19. The frame 18 may be formed of any desirable material, such as the well known extruded aluminum sections or the frame 18 may be formed of wood or other desirable and relatively rigid members. be substantially coextensive with the opening 9, being only relatively small enough to be freely movable into and out of the opening. Any suitable latch device 20, may be carried by the opposite stile 5 to form a means 1 for holding the screen frame 18 in the recessed position.

The screen 18 in the recessed position is substantially flush with the inner side of the door. A suitable knob 21 is connected with one side of the frame 18 adjacent to the latch 20, whereby to manually swing the frame 18 to and from a closure position.

In the use of the device, the panel 10 and the screen frame 18 having been assembled with respect to the door, through the medium of the hinges 11 and 17, the door is then mounted within its respective door opening, by the conventional butt hinges 22. In stormy weather or when the weather is cold, it is desirable that the panel 10 be disposed in the opening 8, constituting a solid exterior closure against the entry of the elements. With the panels 10 in the closed position, the screen frame 18 may also be disposed within its respective opening 9 and whereby the door will function as a conventional solid door. Now, when it is desired that the door constitute a screened door, the screen frame 18 is unlatched and swung outwardly in the direction of the arrow in Figure 4. It is of course necessary that the screen 18 be moved to aproximately a ninety degree angle with respect to the door. 10 swung inwardly to be disposed at any desirable angle with respect to the door, one suggested angle being that illustrated in Figure 5. With the panel 10 shifted to the The screen frame 18 is proportioned to The latch 15 is then released and the panel '3 open position of Figure 5, the screen frame '18 is then again moved into its recess 9 and latched in position so that the screen frame 18 will fully span the opening 8 to be flush with the inner side of the door. The door now constitutes a screened door that permits the free flow of air, yet prevents'the-entry of insects. The door can then be operated in a normal manner, carrying with it the panel 10 and it will be obvious, that the panel 10 whenin the position of Figure 5 will only'be shifted to a predetermined position that permits the normal operation of the door upon the hinge elements 22. When the Weather gets cold or, during a storm, the screen panel 18 can be then swung inwardly from'the door, permitting the panel ltlto be shifted into its opening 8 to abutting relation with the strips 19, forming a solid closure againstthe entry of rain or-the like.

It will be apparent from the foregoing that a very novel form of door construction'has been provided. The door serves a dual purpose, such asa solid panel door or, when adjusted as before pointed out, constitutes a screen door. The structure is simple, is strong, durable, cheap to manufacture and highly advantageous as a multiple closure device. The stepped hinges 11 form a very desirable means for mounting the panel '10 upon the inner face of a perspective stile 5 so that the panel can be completely moved outwardly from the openings 8 and 9 and disposed in a position that will not-interfere with the movement of the screen panel "8. The door frame, including the stiles '5, the header 6 and'the sill 7, While being described as being of wood construction, may obviously be formed of any suitable metallic sections, such as aluminum and the panel 10 may likewise be formed of any desirable material. I

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the subjoined claim.
